JAMES POLLOCK, OF NEW YORK, N. Y., ASSIGNOR TO C. W. HUNT COMPANY, OF WEST NEW BRIGHTON, NEW YORK, A CORPORATION OF NEW YORK.

SEPARATOR.

To all whom it may concern:

Be it known that I, JAMES Pormoex, a citizen of the United States, residing in the borough of Brooklyn of the city of New York, in the State of New York, have invented certain new and useful Improvements in Separators, of which the following is a specification, reference being bad to the accompanying drawings, forming a part hereof.

This invention relates to the separation and classification of the components of a mixture of loose materials, which components differ in their physical characteristics, as in size, shape, specific gravity, surface characteristics, etc.

The object of the invention is to produce an apparatus which shall separate or classify such materials, shall operate evenly and rapidly and shall be reasonably compact.

The apparatus in which the invention is herein shown as embodied has been designed with especial reference to the separation of such materials as coal, ore, gravel, seeds, etc., but is nevertheless capable of use for a wide variety of materials with suitable changes in the relative size and arrangement of the parts.

The invention will be more fully explained hereinafter with reference to the accompanying drawings in which one embodiment thereof is illustrated and in which-- Figure 1 is atop view of a separator constructed in accordance with the invention. Fig. 2 is a view in side elevation of the separator shown in Fig. 1. Fig. 3 is a partial end view seen from the right hand in Fig. 1.

The apparatus shown in the drawings is specially adapted for the separation of a mixture of coal, bone and slate. The mixture may be supplied to the separator through a chute a. The separator comprises a series of plates 0 arranged to deliver from one to another the material to be treated, each of said plates occupying a lower position than the immediately preceding plate of the series and said plates being arranged one in front of another, or off-set with reference to one another, in the direction of flow of the material over said series.

Each plate 0 is inclined slightly from the horizontal, adjacent or successive plates being inclined laterally and in opposite directions so that each of two successive plates slants downward with reference to and to Specification of Letters Patent.

ward the other as shown in Fig. 3. Alternate plates of the series are also preferably oii'set sidewise or laterally with reference to the remaining plates of the series and with reference to the path traversed by the material as it flows over the plates, as shown in Figs. 1 and 3, the extent of such oli'set being variable and being for the purpose of insuring that the material flowing from one plate shall not pass over the side edge of the next plate of the series, and being determined largely by the character of the specific material with which the separator is to be used. The entire series of plates is also inclined downward in the direction of the length of the separator as shown in Fig. 2. For convenience and for the sake of compact arrangement the plates are irregularly quadrilateral, lying at an angle with respect to the axis of the series of plates.

()n the lower side of each plate, with respect to the general direction and inclination of the series of plates, and adjacent to the lower apex of the plate, is arranged an obstruction which is intended to prevent the passage of material from such side or edge of the plate in a direction parallel with the axis of the series and to divert or deflect such material, as reaches the obstruction, upon the next plate in succession. This obstruction to the movement of the material is conveniently formed by a flange (Z at the edge of the plate. The plates are preferably alternately oll'set from the median line of the double series and are inclined toward such median line, that is, the odd numbered plates, for example, are inclined laterally downward to the right and the even numbered plates are inclined laterally downward to the left, so that the material is de livercd back and forth from one plate to another of the series in a zigzag line.

For the handling of any particular material, the characteristics of the components of which remain substantially unchanged, the angle of inclination of the entire series, the angle of inclination of each plate of the series in the general direction of the series and the angle of inclination of each plate of the series laterally do not require to be changed when once determined and the sim plest embodiment of the invention is therefore one in which no provision is made for variation of such angles as illustrated in the drawings, in which the several plates are shown as supported by bracket arms 6 upon a bar 7, the longitudinal dip and lateral dip of each plate being secured through the proper fastening of the plate upon the bracket arm or of the bracket arm upon the bar, while the proper dip or inclination of the entire series is secured by properly supporting the bar 7, as by supports 9, g.

The operation of the separator will be best understood by reference to the heavy dotted lines and the dot and dash lines shown in Fig. l, the heavy dotted lines representing the general path of movement of that component of the material which moves most readily over the plates and the dot and dash lines representing the path of that component of the material which moves least readily over the plates. As the material is discharged upon the separator that component which moves most readily tends to follow the general downward direction of the series of plates. Oneach plate in succession it moves farther toward the lower apex of the plate. The inclination of the plate causes it to fall upon the next plate in succession somewhat lower or nearer the apex, and

from the last plate in the series it is discharged into or upon the discharge chute k at or near the apex of the plate. It will be seen that each plate overlaps the next succeeding plate for a considerable portion of the length of the succeeding plate. The less readily movable material, following generally the path indicated by the dot and dash line, reaches the lateral edge ofeach plate and passes from such plate at a point more remote from the lower apex than the more readily movable material. From the first plate it may fall upon the second plate, and from the second plate it may fall upon the next plate, and so on for some portion of the length of the series but, as indicated by the dot and dash line, its path takes it upon each succeeding plate more directly toward the lateral edge of the plate at a point above the line where it overlaps the nextplate, so that, at all events before it reaches the chute h, it passes over the lateral edge of some one or another of the series without falling upon the next plate or the chute 71. as the case may be. If desired, a chute 71: may be so placed as to receive this less readily movable material which is thus discharged over the lateral edge of a plate without falling upon the next plate. It will now be seen that the paths of different materials are continually crossing one another, the more readily movable material being carried over the less readily movable material upon the overlapping plate while the less readily movable material moves upon the under plate. It will also be understood that the less readily movable material may pass from the series of plates at difierent points along the series, while the more readily movable material able material.

Obviously the size, shape and inclination of each plate, and the inclination of the whole series as well as the arrangement of the plates in a straight line or otherwise may be varied more or less according to the nature of the material to be treated and the invention, therefore, is not limited to the particular construction shown in the drawings.

I claim as my invention:

1. A separator comprising a series of plates over which material may flow and each of which plates occupies a lower position and a position in advance of the next preceding plate with reference to the path traversed by the material as it flows over said plates, successive plates of said series being inclined laterally and in opposite directions so that each slants downward with reference to and toward the other, whereby the material as it flows over said plates from a higher to a lower level will traverse a zigzag and an inclined path.

2. A separator comprising a series of plates over which material may flow and each of which plates occupies a lower position and a position in advance of the next preceding plate with reference to the path traversed by the material as it flows over said plates, successive plates of said series being inclined laterally and in opposite directions so that each slants downward with reference to and toward the other, and each plate being offset laterally with reference to the other, whereby the material as it flows over said plates from a higher to a lower level will traverse a zig-zag and an inclined path.

3. A separator comprising a series of plates over which material may flow and each of which plates occupies a lower position and a position in advance of the next preceding plate with reference to the path traversed by the material as it flows over said plates, successive plates of said series being inclined laterally and in opposite directions so that each slants downward with reference to and toward the other, and each plate of said series overlapping the next succeeding plate, whereby the material as it flows over said plates from a higher to a lower level will traverse a zig-zag and an inclined path.

at. A separator comprising a series of plates over which material may flow and each of which plates occupies a lower position and a position in advance of the next preceding plate with reference to the path traversed by the material as it flows over said plates, successive plates of said series being inclined laterally and in opposite dil rections so that each slants downward with reference to and toward the other, and each plate of said series overlapping the next succeeding plate and each plate being offset laterally with reference to the other, whereby the material as it flows over said plates from a higher to a lower level will traverse a zigzag and an inclined path.

5. A separator comprising a series of plates over which material may flow and each of which plates occupies a lower posi tion and a position in advance of the next preceding plate with reference to the path traversed by the material as it flows over said plates, successive plates of said series being inclined laterally and in opposite directions so that each slants downward with reference to and toward the other and each plate having an obstruction extending across its farther end, as referred to the direction of flow of the material, and each plate of said series overlapping the next succeeding plate, whereby the material in flowing over said plates from a higher to a lower level will traverse a zig-zag and an inclined path.

6. A separator comprising a series of plates over which material may flow and each of which plates occupies a lower position and a position in advance of the next preceding plate with reference to the path traversed by the material as it flows over said plates, successive plates of said series being inclined laterally and in opposite directions so that each slants downward with reference to and toward the other and each plate having an obstruction extending across its farther end, as referred to the direction of flow of the material, whereby the material in flowing over said plates from a higher to a lower level will traverse a zig-zag and an inclined path.
